Hot Plate Stirrers, Hot Plates, and Stirrers, the Analog and Digital EchoTherm Family

Overview

These Hot Plate Stirrers, Hot Plates, and Stirrers share many characteristics and offer options depending on functions desired. The HS series includes hot plate stirrers, the HP series units have similar features except they have no stirring capability and the ST series units are stirrers only. There are choices for control features (analog or digital), plate size and plate material. The HS40 Hot Plate Stirrer and the HP40 Hot Plate are fully programmable. (For information on other fully programmable models check pages devoted to the Programmable EcoTherm Hotplates and Hotplate Stirrers.)

The hot plates are made with a cast aluminum chassis that is painted with chemically resistant epoxy paint. The chassis is designed to keep spills out of the case. The controls are well forward of the heater surface to prevent accidental burns.

The top plates come with ceramic or milled-flat cast aluminum top.

Analog HS10

Digilog HS20

Digital HS51

Programmable HS40

There are three analog models of the HS Series Hot Plate Stirrers, the HS1, HS10 and HS11, which are different in their hot plate sizes (6” × 6”, 8” × 8” and 12” × 12” respectively). In these models, heating and stirring controls are solid state with individual indicator lights, which illuminate when either is activated.

The hybrid model Digilog HS20 has advanced features such as easy setting with membrane keyboard and data storage, but is priced like a simple analog unit.

Digital models of the HS Series Hot Plate Stirrers, the HS30, HS50 and HS51, have an LCD display for the plate and the probe target temperatures, stirring speed and time count (when timer is activated). The stirrer motor speed is optically sensed and controlled by the microprocessor in the unit. Beside the different plate sizes, the models HS50 and HS51 have more features than the HS30 such as the ability to display temperature in either °C or °F and storing up to two sets of data for recall and use.

The HS40 is a fully programmable digital model, with all the features of the other digital models as well as a programmable mode and the ability to store up to 10 programs with as many as 10 steps each. It is part of a family of EchoTherm programmable models, the Hot Plates HP60, HP61,the Hotplate Stirrers HS60, HS61 and HS70 and the EcoTherm 65 5-position Hotplate Stirrer.

Stirrers only, the ST1, ST10, ST11 and ST20

The ST series consists of stirring units with magnetic stirring but without a heating function. Their features are similar to those of corresponding units in the HS Hotplate Stirrer series. However digital models of the Stirrer only ST series are not available.
